BlackBerry 10 is upon us, as we expect RIM to make a formal announcement for the first device in August. Details regarding the BlackBerry 10 operating have been mildly out in the open. However, little has been known regarding the first BlackBerry 10 all-touch smartphone and the eventual physical keyboard iteration, until now.

We previously stated that both the BlackBerry London and Nevada have hit final production. Although, these devices are no longer under those codenames, as we see displayed in the internal document above there is now the BlackBerry L-series and N-series. Here’s some of the known specs…

BlackBerry L-series:

768×1280 screen resolution

55mm wide*

356 PPI

Essentially, the BlackBerry 10 Dev Alpha already has the market ready screen. What will be changed is the final production’s form factor. If you’ve had the opportunity to use a Dev Alpha, you’ll realize the amazing screen quality. The BlackBerry 10 L-series will even beat the iPhone4/S’ retina display, but you’re eyes might not really be able to tell the difference.

Additionally, the internal document above shows the UI structure of the L-series. Now you have an idea of all the measurements for icons and buttons used in the status bar, main bar, tabs and so on.

BlackBerry N-series:

720×720 screen resolution

52 – 53mm wide*

330 PPI

The BlackBerry N-series, which was previously codenamed Nevada, will be the first BlackBerry 10 device with a physical QWERTY keyboard. Think of this device as the BlackBerry 10 Bold. The first N-series is said to use OLED screen technology, but later releases may use LCD display.

The internal document above also shows the UI structure of the N-series. Now you have an idea of all the measurements for icons and buttons used in the status bar, main bar, tabs and so on.

We’re very eager to get our hands on the first BlackBerry 10 final production unit. If what we’re hearing come to fruition, RIM could push the BlackBerry L-series to market as early as the first half of September. The BlackBerry N-series is said to still be on track for a Q1 release in 2013, but we’re hoping it comes out even earlier. Nevertheless, keep it locked to N4BB for the latest breaking news!
